De ce ar trebui să le zâmbim câinilor. Ce se întâmplă în creierul lor când văd o față fericită

Scientists have discovered how dogs' brains respond to human emotions, particularly smiling faces, indicating a positive value for dogs. The study involved 14 dogs in a brain scanner while shown images of human faces. Happy faces activated a reward area in the dogs' brains, similar to how humans experience dopamine release. Previous research showed this area also lights up when dogs anticipate treats or recognize familiar people. The study suggests dogs can differentiate between positive and negative emotions but struggle with various negative ones. This research sheds light on how dogs' brains have evolved through thousands of years of living with humans.
